ARBC hosts legume phenotyping workshop

Posted: June 2, 2014

Legume phenotyping brings root researchers to Arizona from June 3-6.

The Apache Root Biology Center (ARBC) in Willcox, Arizona hosted a legume phenotyping workshop with CG and other collaborators in phenotyping techniques including proximal sensing, shovelomics, roll-up phenotyping and imaging. Participants came from CGIAR and USDA centers and included Hesham Agrama (IITA soybean breeder based in Zambia); Ousmane Boukar (IITA cowpea breeder in Kano, Nigeria); Jana Kholova (ICRISAT physiologist, Patancheru, India); Steve Beebe (bean breeder based at CIAT-Colombia); José Polanía (technician and PhD candidate in the CIAT Bean Program); Jennifer Trapp (bean breeder, USDA-Prosser); Abiezer Gonzalez (technician, U. Puerto Rico); Carlos Rios (data analyst, USDA-Mayaguez, Puerto Rico); Jeff White and Gerard Wall (physiologists at USDA-Maricopa).

Jonathan Lynch led a discussion on the importance of root traits for abiotic stress tolerance.  Steve Beebe spoke on the interconnectedness of edaphic stresses and the importance of selecting for multiple stress environments. Jose Polania presented some of CIAT’s recent findings on pod portioning and pollen viability correlating with yield.

Roll-up phenotyping

Hesham Agrama, Jimmy Burridge, Abiezer Gonzalez, Jennifer Trapp, Jana Kholova and Gerard Wall discuss roll up phenotyping.

Jimmy Burridge led participatory sessions on roll up phenotyping and shovelomics of common bean, cowpea, chickpea and maize.  Jeff White demonstrated his low cost proximal sensing cart on site and differences in plant height and canopy temperature between irrigated and water stressed plots were observed.

Participants discussed convergences between their programs and possibilities for incorporating additional evaluation procedures into their programs.  The group brainstormed on future collaborations and made short and long term plans that include incorporating shovelomics and roll up phenotyping into soybean and cowpea breeding programs.
